Scientists Precisely Edit Human Embryo DNA. Are ‘Engineered Babies’ Next?

Key points

• Scientists Precisely Edit Human Embryo DNA.
• Are ‘Engineered Babies’ Next?
• Published By, Last Updated: June 05, 2026, 10:13 IST Scientists used base editing to alter DNA in human embryos with unusual accuracy, raising hopes of fixing disease-causing mutations but also reviving fears over designer babies.
• Rapid Read The concern is that a technology meant to repair disease-causing mutations could also be used to select desired traits.
• (AI-generated image) Scientists at Columbia University have edited the DNA of early human embryos with unprecedented accuracy, a development that could one day help repair disease-causing mutations before birth but has also revived the long-running fear of babies engineered for selected traits.
